| Market availability1–5 | Available from several mainstream brands[5][7][14] | Available from several mainstream brands[10][11][12] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.75, 0.8 and 1 kg spools[5][7] | 1.75 mm; 0.5 kg spools[10] |
| Typical applications | Stiff high-temperature structural parts — jigs, drone frames and under-bonnet brackets[1][2] | Chemical and automotive parts needing PPS chemistry with structural stiffness[3] |
| Diameter tolerance± mm | ±0.04 (Prusament PC Blend Carbon Fiber)[1] | Not documented |
| Printing Parameters | ||
| Nozzle temperature°C | 285 ± 10 (Prusament)[1] | Not documented |
| Bed temperature°C | 110 ± 10 (Prusament)[1] | Not documented |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[1][15] | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3] |
| Part cooling fan | Off — Prusa allows 0–20 % and warns cooling significantly reduces interlayer adhesion[1] | Not documented |
| Bed surface & adhesion aid | PEI with a glue stick or a commercial adhesive[16] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; the fibre reduces warping against unfilled PC[1][15] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[16][17] | Not documented |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[17] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[15][1] | Expert / industrial hardware only[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[15] | Hardened steel required[3] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[15] | Highly abrasive — standard CF composite[3] |
| Nozzle clog risk1–5 | High — jams from moisture, heat creep or particles; PC already absorbs water from the air and 3DXTech adds a hardened 0.4 mm minimum nozzle, 0.25 mm layers and a 120 °C pre-dry[18][16][19] | High — jams from moisture, heat creep or particles; Polymaker specifies hardened steel or ruby nozzles for carbon-filled PPS and Prusa lists composites as a higher clogging risk[20][19] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[16] | Not documented |
| Hotend requirement | All-metal hot end required (Simplify3D)[16] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h pre-dry[21][22][18] | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][4] |
| Equilibrium moisture content at ~50 % RH% | 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[1] | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][4] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[23] | Not documented |
| Effect of moisture on strength | No dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic and requires a 70–80 °C dry for 6–8 h; run wet, the loss shows as surface defects and poor layer adhesion[17][23] | No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[3] |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[17] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 64 ± 3 printed horizontal and 70 ± 3 printed vertical at yield, ISO 527-1 (Prusament); 3DXTech quotes 73 at break[1][2] | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4] |
| Young's modulusMPa | 2600 printed horizontal and 3200 printed vertical, ISO 527-1 (Prusament); 3DXTech quotes 6980[1][2] | 5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[3][4] |
| Elongation at break% | 4.6 at yield printed horizontal (Prusament); 3DXTech quotes 2.1 at break[1][2] | 1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[3][4] |
| Flexural strengthMPa | 94 ± 3 printed horizontal and 130 ± 2 printed vertical, ISO 178 (Prusament); 3DXTech quotes 85[1][2] | Not documented |
| Flexural modulusMPa | 3500 printed horizontal and 4200 printed vertical, ISO 178 (Prusament); 3DXTech quotes 6540[1][2] | Not documented |
| Charpy impact, notchedkJ/m² | 12 ± 1 printed horizontal and 17 ± 2 printed vertical, ISO 179-1 notched (Prusament)[1] | 5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[3][4] |
| Other impact data | Charpy unnotched 32 ± 5 printed horizontal and 35 ± 4 printed vertical (Prusament, ISO 179-1)[1] | Not documented |
| Layer adhesion / Z tensileMPa | 23 ± 2 (Prusa Polymers interlayer adhesion test) — above the 21 ± 2 of unfilled Prusament PC Blend[1][22] | 32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[3][4] |
| Brittleness1–5 | Moderate[1][2] | Very brittle — cracks or shatters easily; elongation at break 1.4 %[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | 83 Shore D (Prusa Polymers method), against 79 for unfilled Prusament PC Blend[1][22] | Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[24] |
| Creep resistance / sustained load1–5 | Excellent — holds load for years. Room-temperature tensile creep of moulded unfilled PC ran unbroken at 41 MPa until the test was stopped; short carbon fibre raises the flexural modulus from about 2.1 to 3.5-6.5 GPa, which reduces creep strain further[25][1] | Excellent — holds load for years. Ensinger lists high creep resistance for unfilled PPS stock and Spectrum states creep resistance is unchanged under continuous load at high temperature; the fibre raises heat deflection to 252 °C at 0.45 MPa[24][26][3] |
| Fatigue / repeated-flex resistance1–5 | Good. No fatigue test data was found for a carbon-fibre PC filament; the unfilled polymer is rated Good on the same scale[25] | Not documented |

| Glass transition (Tg)°C | 127 (3DXTech, DSC)[2] | 97.7 (PPS-CF10) and 95.0 (PPS-GF20), DSC[3][4] |
| Melting point / Vicat°C | Not documented | 279.7 (PPS-CF10) and 279.6 (PPS-GF20) melting, DSC; Vicat 267.5 and 272.5 (ISO 306)[3][4] |
| Continuous service temperature°C | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[22] | 170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[24] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors unless stabilised[17] | Not documented |
| Chemical resistance | Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[17] | Outstanding — PPS resists essentially all solvents below 200 °C[20] |
| Food contact | Bisphenol-A polycarbonate is not offered as food-contact filament[17] | Not documented |

| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[27] | Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[27] |
| Ultrafine-particle emission rateparticles/min | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[27] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[27][15] | Ventilated room or enclosure recommended[27] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[2] | Fibre is bound in the matrix; sanding dust should not be inhaled[3] |
| Post-Processing | ||
| Sanding & machining | Sands and machines well; the toughness means it cuts rather than chips[16] | Not documented |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[16] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing[16] | Not documented |
| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[16] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[28] | None — PPS does not dissolve in any known solvent below 200 °C.[29][30] |
| Softened or crazed by | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[28] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[30] |
| Solvent welding & smoothing agent | Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[31] | None — no solvent welds or smooths PPS.[29] |
